Subwoofer Eton 12-680/62HEX your suggestion?
 

Hi
I need to make subwoofer for Home Theater so vented box to make high SPL
On Eton 12-680/62HEX. I have this driver already.
Fs=26Hz, Vas=150l, Qts=0.34
BassBox6 gave me Vb=69l, Fb=29Hz, F3=38Hz. I guess this is OK
But your advise will be welcome.

Side firing or bottom firing to make? what is difference?
If bottom firing how high should be driver from bottom?

Why dont you try this one...think you got enough spl from it.

I also have this driver but intend to use it as a sub not over 100hz.

Considering my room size (9x12ft or 3x4m) perhaps a sealed design would supply sufficient SPL

I intend to measure its T/S to get more accurate box predictions.

I've heard this driver in a 4th order bandpass design in the German Ascendo System M loudspeaker and found it extremely musical. In this alignment it rolls off after 120hz.

I'm tossing between sealed and this alignment myself.

How high do you intend to cross at?

I want to buy two Eton 12-680/62HEX
 

Where do I get them and how much do they cost?
